Devil May Cry walkthrough/M11

Let's start this off with a bang!

Walkthrough Part 1
As soon as the mission starts, you will be besieged by Sins. Kill them all to make a floating platform appear. You can jump on the platform to travel around the space and collect some red orbs hanging in mid-air. You may have to jump off to reach some of them. Before proceeding further, you should take a few minutes to gather the goodies scattered around the room.

There's a Devil Star on a platform above the well. Wall Hike to reach the second ledge, then wall hike again to get to the third tier. From there, jump to the floating platform to get the Devil Star.

On the left-hand side of where you came in, (if you're facing the platform that appeared after you killed the Sins,) there is a Blue Orb Fragment hiding in a greenhouse-type hall. You will have to double jump onto a second level, then jump over the wall into the greenhouse. From there, walk towards the far side of the room and towards the blue orb fragment on the pedestal.

When you're ready to continue, jump down the well. You will immediately be attacked by Blades. Take them out, then proceed further. Past the center circular room is a Divinity Statue. On the wall to it's left is a crack: hit it several times with your weapon to break the wall. As soon as you step through, more Blades will confront you. Kill them, and jump all the way up. You'll be in the rectangular greenhouse on the opposite side of the one with the Blue Orb Fragment. Walk to the far end and pick up the Sign of Chastity.

When you jump back down, there will be more Blades to beat up. Kill them all and continue on. A random Blue Orb Fragment will appear, too, in the round room. Jump back up into the main area.

Key item in hand, head through the door that's directly across from the floating platform that appeared after you killed the Sins. Here, you have to jump down to the middle floor. You'll be on the top floor, so just a little jump ought to do it. In a center dias is a place for the Sign of Chastity. Examine it to use the key item and obtain the Chalice. The room will then go into lock down; brick walls will rise up to cover the doors, and the boss fight will begin.

Boss: Nelo Angelo
Nelo Angelo appears again to challenge Dante. Use the same strategy as in Mission 4 to beat him. Just dodge his attacks, and attack from behind.

Walkthrough Part 2
After defeating Nelo Angelo, get up to the third floor again and long jump to the far end, where there will be a little cave with a statue of a knight. Use the Chalice to open the door and proceed through to end the mission.
